I highly recommend a liquid to liquid heat exchanger to make the cooling system more efficient/effective. The oil runs hotter than the coolant. Liquid to air needs thermostatic control for warm up. The svo 2.3l turbo sandwich cooler should fit, aids warm up of the oil and cools it to coolant temp. It will move the filter out by about 2 inches. This is a good deal. These are getting hard to find.

SwjwZcCCpTIf you don't have room at the block and/or think you need a cooler with more capacity and a remote filter, a number of oems have remote liquid to liquid exchangers with integral filter mounts. Most require a plate to be made to install AN8 fittings to accept AN8 flare to 1/2" push loc hose ends. Also need spin on adapter. Don't use a trans cooler since they add a restriction to the oil flow compared to a cooler designed for engine oil.
Here is a higher capacity cooler that you might have room for.

Just need to shorten the dom end enough that it doesn't bottom out on the block before the seal clamps to the block (an old oil filter will provide the right depth). You'd need to use the filter for the cooler application of course.
For max cooling with warm up control, consider this thermostat controlled sandwich adapter and a small capacity liquid to air cooler with push loc an8 lines:https://www.ebay.com/itm/JEGS-51710-Thermostatic-Sandwich-Adapter/312302217309?epid=14012734190&hash=item48b6a9a85d:g:8kIAAOSwNUlb4fxT:sc:ShippingMethodStandard!30180!US!-1:rk:79:pf:0&LH_ItemCondition=1000
I'm guessing you have the 4.10 ratio. I suggest the 3.08 or 3.42 since you have no overdrive. MPG will go up, you will be easier to drive, and the cooling problem may correct itself since you are lowering the generated btus for any given speed.
